    I may have the same problem. The van stalls when i'm at a red light. The van jerks violently when starting from a red light. The engine light comes on sometimes then goes off. The problem happens alot more if i accelerate ofter when the van is warming up. Does anyone have a solution.

To determine what's wrong, u need to have the codes read. If the light is coming on, it is a signal that something is wrong w/ the emissions system. A code is stored in the cars computer that will indicate what the problem is. Most parts stores will read the stored engine codes for free. They plug a scan tool into a port under the dash to retrieve the code(s). Write them down, and ask what u should do to correct the problem. If u have any further questions after that, u can post them here. Let me know how u make out.

My car is chugging it feels like the fuel isn't getting through. I have changed the spark plugs and about to change the fuel filter.


dont just change parts without knowing--scan car at a parts place 1st-------it cud be a failin fuel pump or pressure regulator----or an egr valve--dirty injection system-----worn plug wires------fuel system pressure test or ignition inspection may be in order

1997 Oldsmobile Achieva - check engine light is on and car is running sluggishly...brand new motor installed 6 weeks ago.


What speed are you going when it chugs?
It could be as simple as a bad spark plug or a spark plug wire/boot grounding out.
When spark plug boots get old, the rubber cracks and lets voltage arc out the side and to the engine instead of through the plug.
This will be most noticeable when trying to maintain a speed of over 40 mph, or under mild acceleration.
The reason for being noticeable at this speed/acceleration level is that the transmission torque converter will be locked, transferring the vibration from any engine miss straight through to the wheels.

Ford focus 1.6 zitec petrol, engine warning light flashing, engine chugging, very high fuel consumption, fumes smell when stationary, exhaust seems ok, recently change speed sensor and coil pack?


try the air filter first and the intake.the spark plugs then and after all go to a garage for checking compression timing and the head gasket.

94 Park Ave Ultra intermittent 'check engine soon light' comes on


It sounds like one of the ignition wires is breaking down or possibly a coil. Get a squirt bottle of water and spray a mist on the plug wires and coil to see if a spark starts to jump out. Probably just a bad plug wire.
